The airline saw revenue during the second quarter rise 4.7% to $4.62 billion. Analysts had been looking for $4.59 billion. The number of passengers carried remained flat compared to last year, but prices jumped 4.9% on average, which offset a 3.3% rise in fuel expenses.

Company officials said the airline is on track to produce record annual earnings and will not expand its fleet of jets for at least a year.
